When driving on a freeway entrance ramp, what is the recommended action to find a gap in traffic?

The recommended action to find a gap in traffic when driving on a freeway entrance ramp is to look in your mirrors and turn your head to look over your shoulder. This approach is crucial for safe merging because it allows you to assess the speed and distance of vehicles in adjacent lanes that may be traveling at high speeds. By using both your mirrors and looking over your shoulder, you gain a complete awareness of your surroundings, including blind spots that might not be visible through mirrors alone.

This technique is vital for ensuring that there is a safe gap for you to merge into without disrupting the flow of traffic. It also helps in making informed decisions about when it is appropriate to accelerate and merge onto the freeway. Relying solely on mirrors or only checking your blind spot, as suggested in other choices, does not provide a comprehensive view and can lead to dangerous situations. Additionally, attempting to speed up to merge quickly without adequately assessing traffic dynamics can increase the risk of collisions. Yielding without looking is also unsafe, as it neglects the necessity of situational awareness when merging onto a busy freeway.
